8935CF — Instruction Manual

Installation

 

Cabling

Cabling is done on the rear BNCs of the 8935CF-R module illustrated in 

Figure 10

.

Note

Read the precautions for handling fiber optics before making connections to 
the fiber optic connectors as described in 

Fiber Optic Outputs

 on page 19

.

Figure 10.  8935CF-R Rear Module

Attenuation Requirements

Some shorter length cable runs will require attenuation to prevent over-
driving the receiver causing bit errors to occur on the fiber link. Use the fol-
lowing guidelines for adding attenuation:

The 1310nm Dual Transmitter (SFP-1310-SDTX) requires no attenuation 
between fiber transmitter and receiver connections at any cable lengths.

CWDM devices used with 8939FCA modules for a mux/demux config-
uration (

page 20

) with a cable run from 0-12 km (7.5 miles), must be 

attenuated by 3 dB between 8939CFA COM ports.

All CWDM devices used in a point-to-point configuration with a cable 
run from 0-20 km (12.4 miles), must be attenuated by 5 dB between 
fiber transmitter and receiver connections.
